Travellers who were due to fly at very short notice were permitted to travel on the tickets but those with more notice have had their bookings cancelled.

British Airways is issuing refunds for the cancelled flights as well as a voucher worth £100 on future British Airways flights.

A British Airways spokesperson told Express.co.uk: “We've contacted the small number of travel agents who were able to access the incorrect fare for the short period it was available to advise them and apologise.

“We are fully refunding the tickets that were booked.”

Because the refunds will need to be made through the online travel agents who first sold the tickets, they could take some time to materialise.

With the credit offered by BA, customers can book return trips to Dubai with the airline later this month for around £360 return.

They will not be able to cash in the voucher for flights over Christmas and New Year, however.

Many disgruntled BA customers are not satisfied with the outcome and are questioning whether the airline’s actions are legal.

Under UK law, firms are allowed to cancel purchases if it is clear that a pricing error has been made.

Given flights to Tel Aviv - including taxes, fees and charges - are obviously well over £200, BA can argue that the very cheap fares were a mistake.

However, other airlines do sell tickets to the same destinations for much cheaper than BA.

For instance, Wizz Air is offering flights for £168 return between Luton and Tel Aviv.

A British Airways spokesman told Express.co.uk, "We have apologised to customers and offered a gesture of goodwill. Errors like this are exceptionally rare, and if they do occur, under contract law, there is no binding contract between the parties.

A BA spokesman also told The Independent: “When such mistakes are made, the airline has to make a choice. It is generally able to make a full refund without compensation – though at the cost of negative publicity. Or it can honour the fares.
